Maryann Xue created CALCITE-1182: ------------------------------------ Summary: Add ProjectRemoveRule to pre-processing program of materialization substitution Key: CALCITE-1182 URL: https://issues.apache.org/jira/browse/CALCITE-1182 Project: Calcite Issue Type: Improvement Components: core Reporter: Maryann Xue Assignee: Maryann Xue Priority: Minor
In VolcanoPlanner, we apply a simple pre-processing hep program to normalize the "target" and "query" rels before materialization substitution. Currently this program runs with two rules: FilterProjectTransposeRule and ProjectMergeRule. We need an extra rule ProjectRemoveRule for the Phoenix use case where a secondary index (modeled as materialized views) is defined on a view so the materialized view "queryRel" may have an identity projection introduced by this view. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
